Frequently asked questions

What images work best?
Images with an even white, gray, green, or blue background and clear contrast around the subject work best.
Why are some background pixels left?
Increase tolerance for uneven lighting, then adjust feathering to keep the edge natural.
Will white areas inside the subject be removed?
Only background-colored areas connected to the image edge are removed, so enclosed subject areas are protected.
Does it upload my image?
No. Sampling, processing, and PNG export all run locally in your browser.
Can I export JPG?
Transparent output requires PNG or WebP. JPG does not support transparency.
